Download and setup
Download and setup.
From the download to an unlocked Mac in a few minutes.
1. Download
Get the latest version at justcopy.app/download. It’s the full app, free for 14 days. It needs macOS 14 or later on an Apple silicon Mac.
2. Install
Open the disk image, drag Just Copy into Applications, then open it from there. The short setup asks for the permissions it needs: reading your clipboard, so it keeps what you copy, and pasting, so a card lands where you were typing. File previews are optional.
3. Buy, and find your key
Buy at justcopy.app/price. Right after checkout, Polar emails you your license key, with a link to the download. If it isn’t in your inbox, look in spam for an email from Polar.
4. Activate
Open Settings → License and paste the key. If you bought before you installed, the setup asks for it as you go. Everything you copied during the trial is still there.
Lost your key or the email?
Open your Polar customer portal and enter the address you paid with. Polar emails you a code to sign in, and your license key and the download link are there. The latest version is always at justcopy.app/download too.
A new Mac
On the old Mac, open Settings → License and choose Deactivate this Mac. Then install Just Copy on the new one and paste the same key. One key can be active on up to 10 Macs.
Need a hand?
Email [email protected] from the address you bought with, and say which Mac and which version of macOS you use.
